Took me about two and a half months to complete this swap. Had to do lots of rust repair since this was orignally a Ohio car..... I hate rust. Pulled the old 7mgte and sold it to a local guy it had 3 spun bearings. I put all new Toyota gaskets on the 1JZ installed it and wired up the MS2.

The car is up and running now have cold start and cruising tuned.

I'll post up pics later since I am at work and Photobucket is blocked. So stay tuned.

Here is my HE351VE I picked up for my single swap....

Next to a CT12A

I also found another 1990 supra that is in much better shape then mine so here in the next few months I'll be updating this thread with the new car. So will be going with a single turbo setup with the HE351VE.

Nice Build man. Let me know what HP.

Alright have been having some heat issues under the hood. Built a heatshield last night to help keep some of the heat contained around the turbo and the downpipe. I'll post some more recent pictures later. Also replaced the IAC valve hoses with some -6an SS hose I had left over to clean it up some.

Been doing some more tuning with cruising and some under boost. The Megasquirt with Tunerstudio makes doing this a breeze compared to other standalone's software. The timing map has been a pain in the ass to get timing right so I get a good spool and keeping the EGTs under control.

Also anyone got any good info on EGT temps such as cruising temps etc. During a good cruise for me my EGTs get up around 1100 now and is kinda hot under the hood. Been keeping the cruising AFRs around 14.7:1 - 15.0:1 and timing around 30 to 36 degrees.

Looking great man

Some pictures after I took it out for a drive a tweaked the heat shield just a bit. Going to be installing some 2J cams since it is suppose to rain tomorrow.
